Science: air resistance and revision for quiz

Today was the last lesson our Forces unit.  We looked at air resistance.  We dropped a piece of paper, then scrunched it up and dropped it again.  When it was scrunched up it fell more quickly because its smaller size meant it had less air resistance.  Parachutes increase air resistance so that people fall through the air more slowly.

Next week we will have a short quiz on the Forces unit.  The important points to revise, and the textbook page numbers, are shown on the board above.  The quiz will probably be on Sunday 13 May.
